About PKI Solutions

Pragmatic PKI solutions and training to secure your organization now and in the future

As we become ever more dependent on online services and devices, the need to secure data, electronic transactions and vital information is more important — and challenging — than ever before.

Many of the online services we enjoy today are made possible through the use of public key infrastructure (PKI). A well-designed PKI combines roles, policies, software, and hardware elements to enable secure electronic transfer of information—far more securely than what’s possible with simple password authentication.

While PKI is effective and well-proven, designing and implementing a PKI can be complex, and when it comes to cybersecurity, even small missteps can be costly. That’s where we come in.

At PKI Solutions, we have deep knowledge and experience in all things PKI. Our PKI Microsoft Active Directory Certificate Services (ADCS) training courses are second to none. And we’re ready to help with whatever your organization needs, whether it’s general PKI design and implementation or using PKI to better secure IoT and mobile devices.

Our team is knowledgeable, pragmatic, and responsive.


Mark B. Cooper

President & Founder

Mark B. Cooper, president and founder of PKI Solutions, has been known as “The PKI Guy” since his early days at Microsoft. Mark has deep knowledge and experience in all things Public Key Infrastructure (PKI), including Microsoft Active Directory Certificate Services (ADCS), PKI design and implementation, Internet of Things (IoT), mobile security, and encryption. PKI Solutions provides consulting, training, professional services, and assessments to help ensure the security of organizations now and in the future.

At PKI Solutions, Mark and his team have implemented PKI solutions at enterprises, many of them Fortune 500 companies, in industries including energy, IoT, technology, healthcare, and financial services, as well as federal, state, and local government. Mark has also led hundreds of PKI trainings, including private trainings, across the country and around the world—from Scotland to Buffalo, from Sweden to Washington, D.C.—and everywhere in between. He is also the primary instructor for our online PKI training courses. Mark is also an avid proponent of the SHAKEN/STIR global standard to end robocalls, that uses authentication and PKI to verify callers’ identities.

Prior to founding PKI Solutions in 2014, Mark was a senior engineer at Microsoft, where he designed, implemented, and supported ADCS environments for Microsoft’s largest customers and became the leading subject matter expert for ADCS and identity management. Mark developed and managed the Microsoft PKI Health Check to analyze and report on the design and management of PKI components and created Microsoft’s first consolidated set of PKI best practices. He authored several Microsoft whitepapers, including the specifications and deployment of ADCS on Microsoft Windows Failover Clusters.

Mark has been working with Microsoft technologies since 1992 when he achieved his first MCP certification with Microsoft exam #001. He has subsequently earned the MCSE accreditation for every Microsoft operating system since Windows NT 3.51, and is a Microsoft Certified Trainer (MCT), Microsoft Security MVP, and Charter Microsoft Certified Master—Directory Services (MCM). In fact, for those with Microsoft MCM-Directory accreditation, Mark developed and most likely delivered the PKI portion of the training.
